Mental hypostesia syndrome or numb chin syndrome consists of a sensory neuropathy that leads to the numbness of the lower lip unilaterally in most cases. May be the first manifestation of multiple benign or malignant processes.

The clinical case of a female patient who reports this symptom in isolation is presented. Odontogenic or iatrogenic causes are ruled out. After the CT and MRI study, a soft tissue lesion is seen next to the jaw on the right side and is biopsied with the result of diffuse large B cell lymphoma.

Among the multiple causes of chin hypoesthesia are odontogenic processes, systemic diseases and malignant diseases such as solid tumors of the breast and lung or lymphoproliferative syndromes, mainly.

Keywords : Numb chin syndrome; B cell lymphoma; Biopsy; Head and neck lymphoma.
